If you're ignoring that huge economic event in your analysis of the economics of the latter half of the 19th century, trying to replicate it today is going to be very rough.
Given your other replies in this thread, you're not interested in arguing honestly and I'm not going to continue engaging.
Emancipation isn't Marxist, historically or conceptually.

Absolutely not. "Railroads were the major growth industry," with industrialisation and immigration being the era's economic drivers [1]. "The South remained economically devastated after the American Civil War" and remained a drag on the American economy throughout most of the Gilded Age.
Nothing about that era resembles Marxism, and I’d guess you’d struggle to tell the difference between Karl Marx and the Marx Brothers.
Reconstruction was shut down. Slaves went from assets to contract services. Jim Crow ensured that there was no movement upward. For the aristocracy, they were hurt by the depredation of war but recovered stronger than before under the new system.
The gilded age was about railroads. The south with their feudalist system was a backwater producing mostly raw material. They moved out of irrelevance because social control allowed them to control the Senate for decades.
The government told a bunch of rich people that the incredibly valuable people they owned were no longer their property, and gave money and land to the people who previously had nothing because they hadn't been considered people. That's what kicked off your Gilded Age
